The UNDV 45W P Series is a desktop-type peak-load compatible AC/DC adapter (45W) suitable for equipment that requires instantaneous high current, such as amplifiers, printers, smart speakers (voice assistants), motors, and pumps. It complies with safety standards 62368-1, 60950-1, and PSE Appendix Table 8. Available in four models ranging from 12V to 24V, with three types: UNDVI3045, UNDVB3045, and UNDVC3045.
With a 1-second peak load function, it can output up to twice the rated current, making it ideal for applications such as motors and pumps with high inrush current at startup, and amplifier products that demand instantaneous high power during music playback. Models with an LED display option are also available. Compliant with Energy Efficiency Level VI (ErP/DoE), EU Commission Regulation (EU) 2019/1782, and DOE 10 CFR Part 429 and 430. All models feature energy-saving design with no-load power consumption of 0.1W.
| Why Unifive is chosen: As a power supply manufacturer with over 35 years of development experience, we provide comprehensive support from specification planning and certification acquisition to mass production launch and post-production follow-up, with mass production adoption in mind. Based on standard products, we offer flexible supply from small-lot prototyping and evaluation to small- and medium-scale production, as well as large-volume manufacturing. Semi-custom support is also available, assisting with power supply selection from the specification planning stage toward mass production adoption. |
Key Features
1) 1-Second Peak Load Function - Up to Twice the Rated Current
The key feature of this series is the 1-second peak load function. Designed to deliver up to twice the rated current for up to one second, it supports instantaneous outputs of up to 7.2A for the 12V 4.0A model, 6.0A for the 15V 3.2A model, 4.5A for the 19V 2.5A model, and 3.8A for the 24V 2.0A model. It ensures stable power supply to devices such as motors, pumps, and amplifiers that generate high inrush current at startup.
2) Designed for Amplifiers, Printers, Smart Speakers, Motors, and Pumps
Optimized for a wide range of devices requiring instantaneous high power, including amplifier products, printers, voice assistants (smart speakers), motors, and pumps. It complies with ICT equipment safety standards 62368-1 and 60950-1, rather than household appliance standards (61558-1 and 60335-1), making it suitable for information and communication technology equipment and audio/video devices. Please contact our sales department for details on certifications for each model.
3) LED Display Option Available
An LED display option (/LED model) is available for each type: UNDVI3045, UNDVB3045, and UNDVC3045. The LED allows visual confirmation of the power supply operating status, improving convenience when integrated into products. Please contact our sales department for details.
4) EMC Compliance for ICT Equipment (CISPR 32, EN55035, BS EN55032, BS EN55035)
EMC standards comply with CE CISPR 32 EN55032, BS EN 55032 (emission), EN 55035, and BS EN 55035 (immunity) for ICT equipment. Also compliant with FCC Part 15 Class B and VCCI Class B. Compliance with BS EN standards supports certification for the UK market.
5) High Efficiency 87.77% - Available in Three Types
All four models achieve 87.77% efficiency. Compliant with Energy Efficiency Level VI (ErP/DoE), EU Commission Regulation (EU) 2019/1782, and DOE 10 CFR Part 429 and 430. Available in three types: UNDVI3045 (inline type I plug), UNDVB3045 (B plug), and UNDVC3045 (C plug). Dimensions are 113.50 x 36.30 x 54.00mm for UNDVI3045 and UNDVB3045, and 116.30 x 36.30 x 54.00mm for UNDVC3045. Over-temperature protection (OTP) is available as an option.
